EFHW-16040-2K Multiband band  End Fed Half Wave Antenna

This is an End-Fed Half-Wave (EFHW*) antenna for 160/80/60/40m. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate. It is a resonant Half wave on 160m (1.8MHz) therefore also resonant on the second harmonic of 3.6MHz, the third harmonic of 5.4MHz and fourth harmonic of 7.2MHz. 

*This is perfect antenna for DX-ers  

Various installations such as horizontal, vertical, as inverted V, as inverted L, zigzag etc. are possible. 

NOTE: the minimum height for horizontal portion of the antenna is 0.1 wavelength above ground (~50 feet or 15 meters for 160M band)

  • NO TUNER needed!
  • NO counterpoise needed! (Grounding recommended)
  • Frequency coverage: 1.8/3.6/5.4/7.2MHz
  • Resonant on 160/80/60/40m

    Great antenna for me. Hears almost as well as my old Double Bazooka but it is much lighter and much less maintenance. I would certainly recommend to anyone.

    I have the 16040 and the 10-40 endfeds up and running. For the last several days I was unable to hear VP6AH using 100 watts and a Windom on Pitcairn Island with my 10-40 endfed antenna. Today I switched over to the 16040 antenna and could hear the station on 17 meters. I was able to make the contact. The 160-40 meter antenna worked on 17 meters today when I really needed the help. The 10-40 antenna has given me 73 countries in the last 6 months or so. The myantennas.com endfeds are great antennas.

    Antenna works great good improvement over my window 80 to 10 meter dipole a lot better receive and transmit less noise also and is only mounted 25 feet high in the fat top configuration will buy from again

    After owning the EFHW-8010-HP for several months, and being very happy with its performance (see my review), I decided to add an additional EFHW perpendicularly oriented for 160 through 40 meters. My results have been a bit mixed, but performance on the lower two bands 160m and 80m has been good.

    The antenna feed is mounted at a 4 foot height along the side of my home (brick construction), and runs vertically for 25 feet before taking a long horizontal run to a large tree approximately 200 feet away. I was able to get the end of the antenna strung over the top of the tree at an elevation of roughly 50 feet.

    With the wire provided by myantennas.com, the initial install showed that the antenna was too long for 160/80 — resonances at 1.688 MHz, 3.456 MHz, 5.560 MHz and 7.488 MHz. (Note that the 60 meter and 40 meter bands did not fall near the resonances.) With a simple linear calculation of length versus resonance frequency at the lower end, I removed approximately 25 feet of wire and the antenna was now resonant within both the 160 and 80 meter bands — resonances at 1.838MHz, 3.752MHz, 5.824MHz and 7.888MHz. Now, however, the 60m and 40m bands were even further from resonance. VSWR over the 160 meter band ranged from 1.78 to 4.78:1; while over the 80 meter band VSWR varied from 1.58 to 4.66:1, easily managed with a tuner (2:1 bandwidths were 72 KHz at 160 meters and 152 KHz at 80 meters). Before making these measurements, I added a common mode choke at the antenna feed (this brought the resonance frequencies down a fraction of a percent).

    With the antenna now adjusted for 160 and 80 meters, VSWR over the 7.0-7.3MHz segment exceeded 8.7:1, making the antenna pretty much useless at 40 meters. 60 meters was actually a bit worse — VSWR >10:1.

    From what I have measured, the EFHW-16040-HP is really only useable on 160 and 80 meters. I was disappointed that I could not squeak 40 meters out of it, but it did give me the low band (160 meters) that I was missing. My guess is that the magnetic core material used in the matching network supplied may not be totally suitable for use at the higher frequencies.

    I wanted to add a correction to my previous review on this antenna, and thank Danny from myantennas.com for his help! I hope this review will help others getting this antenna to work well on 160/80/60 and 40 meters.

    As I noted in my Sept 16, 2017 review, the antenna tuned high on the 60 and 40 meter bands, while showing resonance within the 160 and 80 meter segments. Danny pointed out to me that, at a 50 foot elevation, the 160 meter antenna is operating well within 1/4 wavelength from the ground and gets pulled in frequency due to ground effects. (I’m a microwave guy, so “far field” for me is measured in inches! I did not stop and think of the effects on 160 meters.) So, when the antenna is trimmed for proper operation on 160 and 80 meters, it becomes too short on 60 and 40 meters.

    The solution was a simple one. By adding a small coil at a distance of approximately 25 feet from the feed point of the antenna, the two higher resonances now fall within the 60 and 40 meter bands. My initial NEC analysis of the antenna indicated that a value of 4.7uH at 23 feet would yield a resonance at 7.2 MHz. After a bit of trial and error, I ended up using a coil with 12.4 uH of inductance (20 turns on a 1.9″ OD PVC pipe) pushing the resonance down to 7.1 MHz.

    With the additional loading coil, resonances occurred at 1.864 MHz, 3.548 MHz, 5.372 MHz and 7.108 MHz. Perfect!

    Installed the EFHW-16040-HP antenna about a month ago. The feed point is at 9 feet, then the wire is run for 150 feet to an insulator on a tree at a height of 20 feet. From there, the antenna makes a right turn and is run to a tree roughly 110 feet away and secured to an insulator at 24 feet. This antenna performs well on Transmit as well as on Receive on 160m, 80m, and 40m. (Only worked one station on 60m, but it seems to do ok on this band too) I get good signal reports from U.S. and DX stations. The SWR is acceptable on all four bands. I’m running 100 watts with an Icom IC-7300
    The antenna is made well with good quality components. Overall, it’s a great antenna and I’ll probably buy another one in the near future.

    This is a very nice antenna. The wire and transformer are easy to install. I mounted it in a Inverted-L configuration. I have used this by it self and it worked great. When I completed the project, I grounded the antenna and I am also using a counterpoise system that I had already. My tuner easily matches anywhere on the 4 bands. It is a resonate antenna on the lower part of 40, 80, and 160. 60 Meters is acceptable. I have searched a long time for the perfect antenna for the low bands. I am so glad that I found this. I am very satisfied!

    With permission from my neighbor I have installed this antenna from my tower to her pine trees. The antenna is a wonder, and has been used by MANY remote users with my ALS-1306 amplifier. (Remote Hams ABiFF) I only wish I did not live next to the 140KV central Mass. power distribution lines. I believe this antenna is a great performer.

  9. Gabriel,VA2QA

    What a tremendous difference the 160-40 did in my results….160M operations had always been frustrating so far; with this new antenna in the past three months I am up to 41 DXCCs and 43 US states. With spring just around the bend I am looking forward to make a few adjustments in the antenna positionning in order to make it more omnidirectionnal.At the present time the highest point is at 40 feet and the lowest at 5. On 160m,the peak SWR is steady at 1.65/1
    With no hesitation I shall recommend the EFHW 160/40 to anyone seeking to acheive great performance on the lower bands

  10. Kelly Richards

    Bought this antenna with the wire to get on top band.
    The wire is a little long (as it should be for trimming) but thats no problem with a tuner. Fabulous on 160, 80 & 40. Much quieter than my OCF homebrew & I’m hearing stations I previously couldnt. Give it a try, you won’t be disappointed.

    I have had this antenna for the past 2 years in an inv L configuration, between trees. The antenna is very well built. The choice of the wire deserves particular praise. It survived many storms, with the trees swaying left and right. Recently a large tree limb fell on it but did not break the wire. Thanks Danny.

    First Impressions…
    Needed a wire antenna for the 160M band, already have a 80M sloping dipole hanging from a 120′ tower . Mounting this antenna as an inverted V (apex height is 110′) was ideal for my QTH. Snaking feed line through a tall poplar tree is about impossible. Installation convenience is one thing, but how does it play? SWR is under 3:1 over the entire 40, 80 and 160M bands, with no ground connection at the transformer. Both the rig and amp ATUs match this with ease and with no hot RF in the shack. Working 80M EU stations this outplays the sloper (pointed to the EU) by 10-12db! I’m all set for the upcoming 160M ARRL contest.

  13. Aulton WX4SGA

    I have both the EFHW-16040-2K and the EFHW-4010. I can cover all HF bands. My antennas are mounted to the top of a short tower at 30Ft running south up to a very tall pine tree at 100Ft then a turn eastward to another pine for the total of the 259Ft. I do the same with the HFHW-4010 running north to another very tall 100Ft + tree then also eastward. I talk on all HF bands. It has held up through some high winds (40+) with no issues. It is very stealthy, a single wire, is almost invisible unless looking for it.

  14. Aulton

    I am adding additional comments on this antenna. I have use these EFHW antennas almost exclusively over my other HF antennas for close to a year now. I can communicate effectively without the use of an amp most of the time. If you see that the minimum installation height is 50 FT. and go there as a start you will be happy. I talked a friend to installing the same EFHW-16040 and he is very happy with the capabilities. I have my antenna in a L layout and get great signal in NS & EW. My friend has his on 50 Ft pushup poles in a U and gets great signal reports out of Florida.

    I am sorry to see this antenna discontinued because of people not understanding how to properly mount the antenna. I highly recommend this antenna for great signals as well as the stealth of a single wire if mounted properly is almost invisible if using trees for the supports.
